Wärtsilä marine gear boxes to be produced by Siemens

The technology group Wärtsilä and Flender (Siemens AG, Mechanical Drives) have reached an agreement regarding the contract manufacturing of Wärtsilä’s marine gear box portfolio. With immediate effect, the assembly and testing of the gear boxes will be moved to the Siemens Mechanical Drives facilities in Voerde, Germany

By taking advantage of synergies with processes developed at the Siemens plant, the new arrangement will secure the quality and delivery punctuality of the Wärtsilä gear boxes, and will thus provide greater customer value. The design and technical specifications, as well as the delivery arrangements, project management, and interfacing with shipyards and owners will continue to be Wärtsilä’s responsibility.

The gear box is a vital link between a ship’s main propulsion engine and the controllable pitch propeller. Several configurations and sizes are offered according to the actual vessel requirements. Wärtsilä’s gear boxes come in both single and two-speed variants, the latter being of particular benefit to enhance the performance of certain types of vessels.
